STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT

There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art.

The Inventor/Applicant asserts that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant. Inventor/Applicant claims a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum X morifolium and hereinafter referred to by the name ‘G22KOK10PU’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive inflorescence form and ray floret coloration.

The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Oostnieuwkerke, Belgium in October, 2015 of Chrysanthemum X morifolium ‘Sienna Lilac’, not patented, as the female, or seed, parent with Chrysanthemum X morifolium ‘Pandora Pink’, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Oostnieuwkerke, Belgium in October, 2016.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2017. Asexual reproduction by vegetative terminal cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘G22KOK10PU’. These characteristics in combination distinguish ‘G22KOK10PU’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright, outwardly spreading and uniformly rounded plant         habit; moderately vigorous growth habit.     -   2. Freely branching habit; dense and full plant habit; flexible         stems.     -   3. Bright green-colored leaves.     -   4. Uniform and freely flowering habit.     -   5. Long flowering period.     -   6. Medium-sized semi-double type inflorescences with ray florets         that are deep purplish red in color.     -   7. Excellent garden performance.

Plants of the new Chrysanthemum can be compared to plants of the female parent, ‘Sienna Lilac’. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Sienna Lilac’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are more uniformly rounded         than plants of ‘Sienna Lilac’.     -   2. Plants of the new Chrysanthemum have larger inflorescences         than plants of ‘Sienna Lilac’.     -   3. Ray florets of plants of the new Chrysanthemum are deep         purplish red in color whereas ray florets of plants of ‘Sienna         Lilac’ are light pink in color.

Plants of the new Chrysanthemum can be compared to plants of the male parent, ‘Pandora Pink’. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Pandora Pink’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are more uniformly rounded         than plants of ‘Pandora Pink’.     -   2. Plants of the new Chrysanthemum flower about one week earlier         than plants of ‘Pandora Pink’.     -   3. Ray florets of plants of the new Chrysanthemum are deep         purplish red in color whereas ray florets of plants of ‘Pandora         Pink’ are light and dark pink in color.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum X morifolium ‘Lano Purple’, disclosed in U.S. Plant Pat. No. 30,364. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Lano Purple’ in the following characteristics:

-   -   1. Inflorescences of plants of the new Chrysanthemum are         semi-double types whereas inflorescences of plants of ‘Lano         Purple’ are decorative types.     -   2. Plants of the new Chrysanthemum have larger inflorescences         than plants of ‘Lano Purple’.     -   3. Ray florets of plants of the new Chrysanthemum are deep         purplish red in color whereas ray florets of plants of ‘Lano         Purple’ are purple in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a top perspective view of a typical flowering plant of ‘G22KOK10PU’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium under natural daylengths during the autumn and employing cultural practices typically used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 20° C. to 25° C. and night temperatures ranged from 12° C. to 18° C. Plants were 20 weeks old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
